OPTICAL SCANNING DEVICE AND IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240201487 titled 'OPTICAL SCANNING DEVICE AND IMAGE FORMING APPARATUS

The optical scanning device described in the abstract consists of a light source, a rotatable polygon mirror, an optical member, an output portion, and a detector. The device scans luminous flux and controls the light source based on the signal outputted from the output portion and the light quantity detected by the detector.

The optical member guides the scanned luminous flux to an image-bearing member.
The output portion outputs a signal corresponding to receiving the luminous flux.
The detector detects the light quantity of the luminous flux.
A controller controls the light source based on the signal and light quantity.
The luminous flux reaching the detector is reflected closer to the end portion of the mirror's reflecting surface than the flux reaching the output portion.

Potential Applications: - Document scanning - Medical imaging - Industrial quality control

Problems Solved: - Precise scanning of luminous flux - Efficient control of light source

Benefits: - Improved image quality - Enhanced scanning accuracy - Energy-efficient operation

Commercial Applications: Title: Advanced Optical Scanning Device for High-Quality Imaging This technology can be used in industries such as printing, medical imaging, and manufacturing for precise scanning and imaging needs.

Questions about the technology: 1. How does the device ensure accurate scanning of luminous flux? The device uses the optical member and detector to guide and control the light source for precise scanning.

2. What are the potential benefits of using this optical scanning device in medical imaging? This device can improve the quality and accuracy of medical imaging procedures, leading to better diagnosis and treatment outcomes.

Original Abstract Submitted

an optical scanning device includes a light source, a rotatable polygon mirror, an optical member, an output portion and a detector. the optical member guides the luminous flux scanned by the rotatable polygon mirror to an image bearing member. the output portion is provided on an upstream side of the optical member in the scanning direction and outputs a signal corresponding to receiving the luminous flux. the detector is provided on the upstream side of the output portion and detects a light quantity of the luminous flux. a controller controls the light source based on the signal outputted from the output portion and the light quantity detected by the detector. the luminous flux reaching the detector is reflected at a position closer to an end portion of a reflecting surface of the rotatable polygon mirror in the main scanning direction than the luminous flux reaching the output portion.
